Flo Ovulation & Period Tracker

Flo Ovulation & Period Tracker is a health and fitness app by Flo Health Inc. that helps you track menstrual cycles, ovulation, pregnancy, and perimenopause in one place. Many people struggle to see patterns across different life stages because period trackers, pregnancy apps, and menopause tools are usually separate. Flo addresses that by offering a single science-backed tracker that adapts as your needs change, from logging symptoms and predicting fertile windows to following pregnancy milestones and exploring perimenopause symptoms. The app emphasizes privacy with Anonymous Mode and dual ISO 27001 and ISO 27701 certifications, although many of its deeper educational features require a Premium subscription.

Key features

• Cycle and period tracking with support for regular or irregular periods and pre-period symptoms.
• Ovulation and fertile window predictions based on logged period data, plus basal body temperature tracking.
• Over 70 trackable symptoms and moods for more personalized menstrual cycle insights.
• Pregnancy mode with week-by-week updates, visuals, diagrams, expert-reviewed content, and community stories.
• Perimenopause tracking tools including a Perimenopause Score, Menopause Timeline, and logging for sleep, energy, mood, and well-being.
• Anonymous Mode that lets you use the tracker without linking your name, email, or personal identifiers.
• Wear OS 3 compatibility with a tile and complication for cycle insights on your watch.
• Clear cycle summaries you can share with your doctor.

Latest changes

This update is a technical release focused on improving app performance. It does not introduce new features. The change is part of ongoing maintenance to enhance stability and user experience.

Flo is best for users who want a long-term, all-in-one reproductive health tracker rather than separate apps for periods, pregnancy, and perimenopause. It suits people who value privacy credentials and are comfortable with a free core experience plus an optional Premium tier. Experienced users comparing alternatives will appreciate the breadth of tracking options, but those who only need a simple period calendar may find the feature set more than necessary.

Use Anonymous Mode if you want to try the app without connecting personal identifiers. For trying to conceive, log basal body temperature consistently alongside period data to improve fertile window predictions. If you are outside the US, check whether the Symptom Checker is available in your region before relying on it.

Flo remains a strong choice if you want one well-established app to cover periods, pregnancy, and perimenopause with strong privacy credentials. Just be ready to weigh whether the free tier meets your needs or whether Premium is worth the ongoing cost for the deeper insights.
